This application claims priority to provisional application Ser. No. 60/188,617, filed Mar. 13, 2000.
This invention relates generally to food grilling apparatus and, more particularly to a device to control the grill flame, prevent hot spots and to divert of excess fats and greases from grilled foods, when cooked upon a grill, and the like, away from direct contact with the cooking flame.
A large variety of devices have been constructed for either completely shielding the cooking food, as upon the surface of a grill, from the flame, and even in the past, various types of ceramic pads have been formed and which become super heated, through its direct exposure to flame, either from the burning charcoals or the gas flame, and which are interposed between the food being cooked, and the flame, and shield the grilled food and meats from direct contact with the fire. However, it sometimes is desirable to have the foods exposed to a controlled flame for purposes of creating a desired grilled flavor in the foods. Also, it is desirable to have an even cooking surface that reduces hot spots. Therefore, it would be desirable provides means for both controlling the flame and diverting the excess greases that drip from the grilling food, so as not to completely block the grilling food from the flame but retard flare ups and burning or scorching of the food. It also would be desirable to provide some means for regulating the contact of the fire with the grilling food, during usage of a gas or charcoal burning grill.
This invention relates generally to an accessory for application to a gas grill, and more specifically to a flame controlling device, and which may also include a grease diverter, when the gas grill or charcoal grill is being used. The device is designed to create a more even cooking surface and reduce hot spots.
This device can be used as the actual grilling surface, or it can be affixed below the normal grilling surface found on most gas grills and interposed between the grilling surface and the heat or flame source. When used as the actual grilling surface, the products being grilled will be placed directly upon the surface. When the device is not being used as the grilling surface, the products being grilled can be placed on the standard wire grill above the heat source found on the gas grills, with this invention affixed or suspended or otherwise positioned below the grilling surface. The function of the device when applied in this manner is also for use with a grease diverter. The general functional application of this invention is to allow the user the enjoyment of the traditional grilling process, while grilling his/her foods, while at the same time preventing grease related fires from erupting, as normally associated with meat drippings, as well known in the art, and also to provide for a more uniform dispersor of the cooking heat.
The construction of this device is as follows: The device has a top surface which and includes a plurality of inverted pyramids, being hollowed on the inside, that allow meat drippings to flow away from the product being grilled. Each inverted pyramid is attached integrally to an adjacent pyramid, thus providing a matrix or plurality of such pyramids in a single plane. Each pyramid has a hole or drain in the lower end, or at its lower tip, to allow drippings to escape. Adjacent sides of each pyramid converge to a pointed crease which angles downward to the drain. The pointed creases function to prevent the fat drippings standing or puddling. The angles of the slope of the walls of the pyramids leading from the top, or the grilling surface, to the bottom of the of the device, is such that the fat drippings from the grilled product will exit quickly, and not allow the fat drippings to accumulate or puddle up, as can be understood.
In an alternate construction, rounded or cone-shaped funnels may be used for the same purpose, connected into a grid pattern, using the same principle as described in the pyramid shaped construction previously defined. The round shapes may also converge together and are interconnected to make a flat grid that results in the top surface. In these the flat areas, additional venting or slots or holes may be used and constructed into the surface. These venting slots or holes are incorporated in the flat areas between the cones throughout the extent of the top surface. The construction of round funnel shapes into a matrix can leave the identified flat areas at the area next to the funnel, and adjoining other common funnels formed into the grilling surface. Whether constructed in the adjoined pyramidal fashion or the cone fashion, the device of the present invention can be used at the grilling surface itself or suspended below a grilling surface and above the heat source to spread heat, control grease flow and retard flames.
A further modification to the construction of this invention is to provide a grease diverter under the aforesaid grilling surface with the grease diverter including flat sloping panels in the direction laterally from the midpoint. The panels have a series of slots formed therein to allow heat or flame to rise through the grease diverter. These specially constructed sloping flat areas spread heat and provide for directional funneling of a substantial amount of the excess grease drippings to drains found in the body of the grill. However, a lesser amount of the grease can exit through slots provided through the sloping flat surfaces.
The device can be constructed from cast metal, formed metal, or stamped metal. Obviously, construction of the invention is not limited to these types of methods, as can be understood. Optional ceramic, porcelain, Teflon or other hardened coatings can be applied to enhance the performance of, but the invention is not limited to any of the identified materials. In fact, it is known that ceramic or molded cement, can be used to perhaps construct this type of invention, and yet provide various funnel like openings, along its molded construction, when forming the grilling surface of this invention.
It is, therefore, the principal object of this invention to provide a molded or formed grilling surface which can function both as a flame control means, in addition to providing a grease diverter, for a gas grill.
Another object of this invention is to provide a grilling surface that can regulate the degree and quantity of flame, and heat, that attains access to the food being grilled, through its intermediate arrangement between the food supporting grilling surface, and the flame generated therebelow.
Another object of this invention is to provide for various shapes to the supplemental grease diverting device, of this invention, and which allows for the controlled flow of any generated grease, away from the food surface, and even when dripped upon the flame, will prevent the direct access of the flame to the food being cooked.
These and other objects may become more apparent to those skilled in the art upon review of the summary of the invention as provided herein, and upon undertaking a study of the description of the preferred embodiment, in view of the drawings.
In referring to the drawings,
Corresponding reference numerals indicate corresponding structures throughout the various drawings.
In referring to the drawings, and in particular
The grilling surface 20 of this invention includes a plurality of integrally connected inverted pyramid like members 32, which normally will be fabricated from durable materials as cast iron or other metal, and into the configuration as best can be seen in
In the illustrated embodiment, the pyramid members 32 are arranged in rows, as shown, to make a generally rectangular grilling surface. In these figures, there is shown the top view of the grilling surface in
A modification to the invention is shown in
Thus, as can be seen from the description of the invention as provided herein, the object of this invention is to provide a grilling surface, generally stamped from metal, and configured either as a series of integrally connected inverted and truncated pyramids, or truncated cones, as explained herein. The object is to allow for the grease to eventually drip downwardly, as the food arranged directly upon the grilling surface 20, 20′ or on the wire grill 46 as used with the gas grills, becomes cooked, but at the same time, this grilling surface 20, 20′ functions to allow heat to penetrate upward while it retards the direct access of any flame that may be caused when any grease falls upon the gas burner.
In operation, when used as a grilling surface 20, 20′ is made in such a way that the positive open air heat transfer is at a much smaller ratio as compared to the negative non-open air heat transfer of prior art grills. The open-air transfer will allow one to have the benefits of a flame grilled product. The negative air flow will allow heat to transfer to the product for cooking, but controls the flame and reduces the possibility for grease fire flare ups.
The grease diverter 50 is a bent piece of material, as previously discussed, and has various holes or slits 56 placed at various locations through its surface. This construction allows the flame to disperse and pass through the device, to assist in a more even flame cooking of the product being cooked. In addition, while also allowing the flame or heat to pass, the device allows for a small percentage of the fat drippings to pass through the so that when heated provide some amount of flavor. In addition, when a substantial amount of the fat drippings make contact with the diverter 50, there is a dispersion or separation, with most of the grease either flowing down to the front or back edge of the diverter and away from the heat source for removal from the base of the grill.
Variations or modifications to the subject matter of this invention will occur to those skilled in the art upon reviewing the development as explained herein. Such variations or modifications, if within the spirit of this invention, are intended to be encompassed within the scope of this invention as defined and the appended claims. The description of the preferred embodiment as provided herein, for this invention, is done for illustrative purposes only.
